ive been geting my replacment batteries from Digiprintuk and found them to be of a higher power in most cases then originals.

Plus baring in mind Nikon had a product recall for there batteries due to melting im quite happy i use originals.

So far, it's great. Lasts just about twice as long as the stock Sharp EA-BL06, under my normal use, which includes checking emails etc. by my hospital's wireless access during my coffee breaks and lunch.Where the stock battery would last me 1.5 to 2 hours, the Lauter special (hi, Ludwig!) lasts 3 to 4 before it really really wants a recharge.
